            This is the default implementation of a ColumnModel used by the Grid. This class is initialized
with an Array of column config objects.
<br><br>
An individual column's config object defines the header string, the <a ext:cls="Ext.data.Record" href="output/Ext.data.Record.html">Ext.data.Record</a>
field the column draws its data from, an otional rendering function to provide customized
data formatting, and the ability to apply a CSS class to all cells in a column through its
<a ext:cls="Ext.grid.ColumnModel" ext:member="id" href="output/Ext.grid.ColumnModel.html#id">id</a> config option.<br>
<br>Usage:<br>
 <pre><code>var colModel = <b>new</b> Ext.grid.ColumnModel([
	{header: <em>"Ticker"</em>, width: 60, sortable: true},
	{header: <em>"Company Name"</em>, width: 150, sortable: true},
	{header: <em>"Market Cap."</em>, width: 100, sortable: true},
	{header: <em>"$ Sales"</em>, width: 100, sortable: true, renderer: money},
	{header: <em>"Employees"</em>, width: 100, sortable: true, resizable: false}
 ]);</code></pre>
<p>
The config options listed for this class are options which may appear in each
individual column definition.        </div>

        <strong>Parameters:</strong>
        <ul><li><code>eventName</code> : String<div class="sub-desc">The type of event to listen for</div></li><li><code>handler</code> : Function<div class="sub-desc">The method the event invokes</div></li><li><code>scope</code> : Object<div class="sub-desc">(optional) The scope in which to execute the handler
function. The handler function's "this" context.</div></li><li><code>options</code> : Object<div class="sub-desc">(optional) An object containing handler configuration
properties. This may contain any of the following properties:<ul>
<li><b>scope</b> : Object<p class="sub-desc">The scope in which to execute the handler function. The handler function's "this" context.</p></li>
<li><b>delay</b> : Number<p class="sub-desc">The number of milliseconds to delay the invocation of the handler after the event fires.</p></li>
<li><b>single</b> : Boolean<p class="sub-desc">True to add a handler to handle just the next firing of the event, and then remove itself.</p></li>
<li><b>buffer</b> : Number<p class="sub-desc">Causes the handler to be scheduled to run in an <a ext:cls="Ext.util.DelayedTask" href="output/Ext.util.DelayedTask.html">Ext.util.DelayedTask</a> delayed

handler is <em>not</em> invoked, but the new handler is scheduled in its place.</p></li>
</ul><br>
<p>
<b>Combining Options</b><br>
Using the options argument, it is possible to combine different types of listeners:<br>
<br>
A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)
<pre><code>el.on(<em>'click'</em>, <b>this</b>.onClick, <b>this</b>, {
    single: true,
    delay: 100,
    forumId: 4
});</code></pre>
<p>
<b>Attaching multiple handlers in 1 call</b><br>
The method also allows for a single argument to be passed which is a config object containing properties
which specify multiple handlers.
<p>
<pre><code>foo.on({
    <em>'click'</em> : {
        fn: <b>this</b>.onClick,
        scope: <b>this</b>,
        delay: 100
    },
    <em>'mouseover'</em> : {
        fn: <b>this</b>.onMouseOver,
        scope: <b>this</b>
    },
    <em>'mouseout'</em> : {
        fn: <b>this</b>.onMouseOut,
        scope: <b>this</b>
    }
});</code></pre>
<p>
Or a shorthand syntax:<br>
<pre><code>foo.on({
    <em>'click'</em> : <b>this</b>.onClick,
    <em>'mouseover'</em> : <b>this</b>.onMouseOver,
    <em>'mouseout'</em> : <b>this</b>.onMouseOut,
     scope: <b>this</b>
